The current French EP regulation called “RT 2012” imposes a maximum airtightness level2 of residential buildings envelope: 0.6 m3.h-1.m-2 for single-family houses and 1 m3.h-1.m-2 for multi- family buildings. The respect of these requirements must be justified either with an airtightness test of each building or by the application of a certified quality management approach on the building airtightness. In both cases, airtightness tests must be performed by a third-party tester, qualified by the certification body, Qualibat.

Purpose of the work
Many ventilation systems do not work efficiently, because their airflow rates have not been correctly adjusted and due to leakages of the ventilation ducts and individual elements.
Method of approach
Different measuring devices are used to evaluate and adjust the flow rates, to conduct airtightness tests with differential pressure measurements of ventilation systems or their parts, as well as to search for leakages of ventilation components.

Purpose of the work
Since 2008 in France, all measurement of building envelope airtightness performed according to the EP-regulations have to be performed by a certified operator. This certification includes a yearly follow-up we use to build up a highly detailed database which includes data of about 90,000 airtightness measurements.

Large buildings can not always be tested as a single pressure zone. In Europe, different approaches have been proposed concerning the choice of representative parts of the building (sampling method) and the compliance check in situations, when several parts of the building have to be tested separately. The preliminary Czech standard TNI 73 0330 defines a sampling method, as well as subsequent treatment of results and compliance check procedures for multifamily residential buildings. This contribution reports the results of a trial test of TNI 73 0330 method.
